Product Introduction
The Honeywell DC-TDOD51 51307611-176 Digital Output Module is a high-performance, isolated digital output (DO) module, purpose-built for use in Honeywell Experion PKS, C300 Controllers, and Series C I/O environments. It offers 16 channels of isolated, high-reliability digital output for controlling a wide variety of field devices such as motor starters, solenoids, interposing relays, alarm annunciators, lighting circuits, and safety interlocks.
Each of the 16 channels is individually isolated, ensuring maximum protection against electrical transients and cross-talk. The module provides fast switching performance, extensive channel diagnostics, and LED indication to ensure high availability and easy maintenance — all vital in demanding process industries where uptime, reliability, and safety are critical.
Widely deployed across industries such as oil & gas, chemicals, power generation, water treatment, mining, pulp & paper, and life sciences, the DC-TDOD51 enables Honeywell control systems to deliver precise and robust on/off control in even the harshest operating environments.
